JAMES GOCI-IRAN, 0F LOCKPORT, NEW YORK, ASSIGNOR TO THE NIAGARA COTTON &BATTING COMPANY, OF LOCKPORT, NEW YORK.

BAT CUTTING AND ROLLING MACHINE.

To all whom it may concern."

Be it known that I, JAMES CocHRAN, a citizen of the United States,residing at Lockport, in the county of Niagara, State of New York, haveinvented certain new and useful Improvements in Bat Cutting and R llingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to devices for rolling up bats of the materialcommonly known as cotton batting and cutting ofi" definite lengths ofthe material. In the manufacture of such devices as bed comforts andother articles of the like character the operation of preparing thelining of such comforts is attended with considerable annoyance due tothe fact that the rolls of batting have to be cut or pierced in orderthat they shall be of the right lengths.

One object of the present invention is to provide a machine which willroll up lengths of batting and cut the same squarely so that each rollwill have precisely the same length of batting contained therein or willconsist of a plurality of lengths each of which equals the other lengthsin said roll. In cutting a soft and very pliable material such as cottonbatting much difiiculty is experienced owing to the tendency of thebatting to jam between the shear blades unless the ends be properlytensioned and the blades be held so that their edges will move in veryclose relation to each other.

A second object of the present invention is to provide an improved meansfor tensioning the bat during the cutting operation. In a machine ofthis description it is necessary to have some form of feeding device andit is essential that the feeding device feed the material to the shearsso that the operation may be continuously carried on. With a lightmaterial like batting there is a marked tendency for the material tostick to the shears and thus clog the space between the feeder andshears by refusing to slip through when the shears are open.

A third object of the present invention is the provision of novel meanswhereby the feeding mechanism ceases to feed during the effective orcutting operation of the shears.

A fourth object of the present invention Specification of LettersPatent.

the shears so that it may be readily sheared.

In the formation of rolls of batting it is not desirable that thebatting be heavily compressed as when this is done it loses its fluffyand elastic nature and its heat insulating qualities are therebydestroyed.

A fifth object of the invention is the provision of a novel mechanismfor forming a roll which is so arranged that after the roll has reacheda certain size the roll being formed will be released from otherpressure except that due to the weight of the material.

With the above and other objects in view, as will be hereinafterapparent, the invention consists in general of a machine embodying afeeder, a shear and a roll forming device, the several features and theentire mechanism being all of novel form and construction and actuatedby improved operating mechanism.

The invention further consists in certain novel details of constructionand combinations of parts hereinafter fully described, illustrated inthe accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and :Figure 1 is a side elevation of amachine constructed in accordance with this invention. Fig. 2 is a planview of such a machine. Fig. 3 is an elevation of the front or receivingend of the machine. Fig. 4 is an elevation of the rear or delivery endof the machine. Fig. 5 is a cross sectional view on the line 55 ofFig. 1. Fig. 6 is a sectional view of the shearing mechanism, the viewbeing taken on the line 66 of Fig. 2. Fig. 7 is a detail view showingcertain mechanism at the end of the machine adjacent the knife. Fig. 8is a detail view of a gallows frame used in connection with the cut-oifmechanism.

The main frame of the invention includes upright members 10 and 11. Themembers 1.0 are preferably termed the front uprights and the members 11the rear uprights. The front uprights 10 are connected by suitabletransverse members 12 while the rear uprights are provided with brackets13 to secure them to a floor or other foundation.

Connecting the upper ends of the members 10 and 11 on each side of themachine is an upper longitudinal frame member 14 and running between thesame uprights adjacent their lower ends is a longitudinal frame member15. The members 14 are provided with suitable bearings for the receptionof a transverse main shaft 16 and in alinement with these bearings is abearing 17 carried on'a bracket 18 secured to the main frame,

said bearing 17 forming the out-bored bear-' ing of the shaft 16.Between the main frame and the out-bored bearing 17 are the fast andloose pulleys 19 which receive the driving belt of the machine. Theuprights 10 have secured thereto certain bearings which support a shaft20 preferably termed the cam shaft. On this cam shaft is a large gear 21which meshes with a pinion 22 carried on an idler shaft 23. On thisidler shaft is also fixed a gear 24 which meshes with a gear 25 carriedon the shaft 16. By means of this gear train just described the rotationof the shaft 16 will cause the gear 21 to rotate.

As will appear from what is hereinafter set forth the lengths of thebats are determined by the rotation of the gear 21, the arrangementbeing such that with every rotation of said gear 21 the shear isactuated to cut the bats off. Now, by a proper adjustment of thisportion of the device by means of different sized gears the lengthsdesired to be cut off may be regulated It is to be particularly notedthat the term bat as used throughout the specification and claims is notto be limited to the folded stock but may also include single sheets ofcotton such as are commonly termed mattress stock.

Located on the members 14 and projecting up therefrom is a gallows frame26 having suitable guides 27 secured to the inner faces of the uprightportions and these guides may be adjusted to or from each other bysuitable means, the preferred means being a tapered gib 28, theconstructionbeing best shown in Fig. 6. Extending across between themembers 14 and located between-the lower ends of the upright members .ofthe gallows frame is a stationary knife support 29 whereon rests thelower or stationary knife 30. This knife is held securely to the support29 by means of bolts 31 and may be adjusted to proper position on saidsupport by bolts 32 passing through suitable lugs 33. Extending over thestationary knife and the bolt heads is an apron 34 the purpose of whichwill be hereinafter explained.

Sliding between the guides 27 is a movable knife support 35 whereto issecured a blade 36. By means of the gibs 28 and bolts 32 the edges ofthe two knives forming the shear may be kept in proper relation so thatthey just graze each other, thus preventing the material being drawnbetween the sides of the knives and insuring the proper shearing. Tothis end also the movable knife 36 of the shear is set at an angle ascan clearly be seen by reference to Fig. 3.

Extending upward from one side of the gallows frame 26 is a bracket 37having a forked upper end 38 wherein is pivoted a bent lever 39.Connecting one end of this lever with the frame 35 is a link 40. Theother end of the lever 39 lies vertically over the shaft 20 and projectsslightly beyond said shaft. Depending from this end of the lever is alink 41 which has a rounded lower end 42 and this lower end movesbetween roller guides 43 supported on a suitable base block 44 securednear the end of the machine. By this means the link 41 is properlyguided. Secured to the shaft 20 is a cam 45 and on the link 41 is aroller pin 46 which engages the edge of the cam 45. This cam is soarranged that once during each revolution the roller pin 46 will beallowed to move suddenly upward, thus permitting the dropping of theframe 35 carrying the upper member of the shear. To aid in pulling downthe frame 35 the lower end of said frame is provided at each end with alink 47 and to the lower end of each of these links is connected theupper end of a spring 48, the respective lower ends of said springsbeing connected to a cross bar 49, the ends of which move betweensuitable guides 50 secured to the frame. This cross bar 49 may bedepressed to increase the tension of the springs 48 by means of bolts 51which pass through plates 52 having threaded apertures therein, theheads of these bolts resting on top of the cross bar 49. These bolts 51are also provided with suitable lock nuts 53 to prevent accidentalderangement of the spring tension. By means of this arrangement when theroller 46 is allowed to move upward the springs 48 draw the knife 36quickly down and insure the cutting of the material. It is further to benoted that by varying the tension of these springs the shear may beadapted for cutting different weights or thicknesses of the material.

Extending upward from the members 14 adjacent their forward ends arebearing guides 54, these guides being positioned inside of the members14. On the members 14 opposite these guides are bearings 55 wherethroughpasses a shaft 56 which is provided with a feed roller or drum 57.Slidable in the guides 54 are bearings 58 supporting a shaft 59 fixed towhich is a feed roller 60. The bearings 58 are normally pressed downwardby means of springs 61 the pressure of which is regulated by tensionbolts 62 passing through threaded plates 63 at the upper ends of saidguides. By means of this arrangement the proper tension may bemaintained between the rollers 57 and 60. Furthermore, the shafts 56 and59 are provided at one end with meshing gears 64 and 65, the gearshaving long teeth so that the separation of the rollers due to materialpassing between may not cause the gears to unmesh. shaft 56 is alsoprovided with a gear 66 on the end opposite the gear 64. In thepreferred construction the roller 60 is of considerably less diameterthan the roller 57 and in order to make these two rollers move at thesame peripheral speed the gears 64 and 65 have the same tooth ratio asthe diameters of the respective rollers. In order to properly feed thematerial the roll 57 is covered with cloth, heavy cotton cloth such aslight duck being preferably used for this covering.

At 67 is a shaft which lies directly beneath the shaft 56. The end ofthe shaft 67 adjacent the gear 64 is loosely fitted in a vertical slotin a suitable bearing so that it may move slightly to permit the otherend of the shaft raising and lowering. The other end of this shaft 67passes through and is journaled in a lift link 68 the lower end of whichis slotted as at 69 to receive the shaft 20. On this shaft 67 is a gear70 which meshes with the gear 24 and with a gear 66 carried on the shaft56. On the lift link 68 is a roller 72 which normally rests on a cam 73fixed upon the shaft 20.

This cam is so arranged that during a portion of its revolution the liftlink is raised and the shaft 67 moved up so that the gear 70 is held inmesh with the gear 66 while during the remainder of its revolution theshaft is moved down and the gear 70 allowed to drop out of mesh with thegear 66, thus stopping the motion of the rollers 57 and 60, whichconstitute the feeder for the machine.

It is to be noted that the arrangement of the cams 7 3 and 45 is suchthat at the time when the feeder stops moving the shear will operatewhile during the time that the shear is idle the feeder is in operation.The purpose of this will be understood when it is considered that thesoft and fluffy material of which the bat is composed will pile upagainst the side of the knife blade as the feeder is allowed to operateat the time when the blade is down. The stopping of this feeder has alsoanother purpose in connection with tensioning the material beneath theknife during the shearing operation. This purpose will be bestunderstood from what follows hereafter.

In order to convey the material away from the shear it is preferred touse a conveyer composed of a plurality of rolls although some other formmay be found equally adapted for the purpose. In the present instancethere is here shown a con- The veyer composed of spaced rolls 74, 75 and76. These rolls are all carried on similar shafts 77 mounted in suitablebearings on the members 14 and each of these shafts has fixed thereto agear 78. The gear 78 of the roll 74 meshes with the gear 25 and betweenthe adjacent rolls 74 and 75, and 75 and 76, are idler gears 79 whichmesh respectively with the gears of the rollers above noted. Carried insuitable bearings 80 on the members 14 is a shaft 81 whereon is a gear82 which is connected to the gear of the roller 76 by an idler gear 83.On this shaft 81 is a roller 84 which is so arranged that it projectswell above the roller 7 6. Pivoted to the shaft 81 are arms 85 and tothe free ends of these arms are secured extension arms 86 which areconnected to the respective arms 85 by a bolt and slot connectionindicated at 87. By this means the arms 86 may be adjusted relative tothe arms 85. Journaled in the free ends of the arms 86 is a shaft 88whereon is mounted a roller 89. On the shaft 88 is also a sprocket 90and on the shaft 81 is a similar sprocket 91, the two being connected bya sprocket chain 92. By means of this arrangement it will be noted thatall of the rolls 74, 75, 76, 84 and 89 revolve in the same direction. Itis also to be noted that the adjustment of the arms permits theadjustment of the roller 89 to or from the roll 84. The roll 84 ispreferably termed the lifting roll and the roll 89 the returning roll.The roll 89 1s so connected by the sprockets and chain that this rollhas a higher peripheral velocity than any of the other rolls.

Journaled to bearings 93 secured to the rear of the members 11 is ashaft 94 whereon is supported a lever 95 which has its upper endconnected to a shaft 96, the ends of which carry links 97, the otherends of said links being connected to the shaft 88. EX- tending forwardfrom the lower end of the lever 95 is a bracket 98- from the forward endof which depends a weight 99, the arrangement being such that the roll.89 normally projects over the roll 76 and lies closer to the front ofthe machine than the roll 84. In order to limit the movement of thisroll 89 in a forward direction a suitable stop is provided. This stop isindicated at 100 and moves between guides 101 which are secured to sideboards 102 projecting upward from the members 14, there being two ofthese stops, one lying in the path of each of the arms 86. These stopsare slotted as at 103 and bolts 104 serve to hold them in adjustedposition. J ournaled to suitable bearings 105 carried on the members 11is a shaft 106 whereon is a sprocket wheel 107 which is connected bymeans of a chain 108 with a sprocket wheel 109 fixed to the shaft 20. Onthis shaft 106 is a cam 110 which is so arranged asv to engage againstthe member 95 and push that member forward, thus drawing the roller 89away from over the roller 76, the cam being arranged to do this at apredetermined time as will be understood from the operation of themachine. The respective rollers 75, 76, 84 and 89 are all covered withthe same material as is used to cover the roller 57.

In the operation of the device the mate rial is started between the feedrollers 57 and 60 by hand and the belt thrown on the fast pulley. Aspreviously noted the usual length of material in one roll is seven feetor any multiple thereof, although any other suitable length may be usedby changing the gear ratio between the gears 21 and 25 as also notedabove. As the material passes beneath the movable blade of the shear itruns over the rollers 74-, 75 and 7 6 until it strikes the lifting roll84. The frictional engagement of the end of the material with thelifting roll raises the end of this material up until it strikes theunder portion of the returning roll 89. Now, as this roll is rotating inthe same direction with the other rolls it will move this end of thematerial toward the front or feeding end of the machine. This end willthen fall downward on top of the material which is moving toward thelifting roll 84 and as a result of this operation, will start to rollup. When suflicient of thismaterial has been rolled up tost-art thecenter of the roll in a neat cylindrical form the high velocity of theroll 89 will carry this center out from against the roll 84 so that itwill lie in the valley between the rolls 75 and 7 6. At this time thecam 110.comes into play and moves the roller 89 away from over the nowrapidly forming roll of material. It is to be noted that where thinmaterial of any sort is used such as a single bat it is not necessary tomove the roller 89 and the sprocket chain 108 may be disconnected, butwhere heavier material isused the roller 89 would be in the way of theformation of the complete roll and is, therefore, arranged to be movedout of such position by said cam 110. Now, the friction of the coveredsurfaces of the rolls 75 and 76 will continue the rolling up of the rollof material without. compressing the same to an undue degree. When theseven feet or other length for which the machine has been set, haspassed beneath the movable blade of the shear the cams 45 and 73 comeinto action. The cam 73 is so positioned that at this time the feeder isdisconnected from the driving gear. Meanwhile the rolls 75 and 76continue to move. The material is thus held fixed between. the feederrolls and tensioned by the action of the rolls 75 and 76. At thisparticular time the cam 45 releases the pin roller 46 and the uppershear descends and severs the material. As previously noted the materialis not moving at this time and there is no accumulation of materialbetween the feeder and the shear. As the fresh length of material startsin, due to the shear being raised by its cam and the feeder again throwninto operation, the rolls 75 and 76 will complete the rolling of thematerial which may then be removed if a single length roll is desired tobe formed. If, however, a roll of several lengths is desired to beformed the first roll is left in position. The end of the material willthen engage between the roller 75 and the roll resting thereon and clingto the roll of material which has just been formed. The former operationwill then be repeated with the exception of the fact that the liftingand returning rolls will not come into play, the material being rolleddirectly on the already formed bat roll. There has thus been provided asimple and efficient device of the kind described and for the purposespecified.

It. is obvious that minor changes may be made in the form andconstruction of this invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described, but it is wished toinclude all such as properly come within the scope of the appendedclaims.
